Brian,
The number of turns is just a measure of the steering box gear ratio. It does not affect handling other than how much you have to turn the steering wheel to turn the tires a certain angle. The wrong steering box might be an issue, possibly even damaged the lower control arms if it doesn't have the turn stops clocked the same as Billy mentioned, but your steering problem lies elsewhere.
I am also solidly in the truck-alignment-shops-don't-understand-our-GMCs. I did a "get it drivable" alignment after I put on the one ton front end, got it close but not right, and brought it on recommendation to a truck service shop that had just had a new Snap-On alignment station installed to the tune of $150K. I was the first vehicle brought in and the Snap-On rep with his assistant was training the 3 shop mechanic on how to use the setup. Long story short, their alignment was better than my initial, but still not quite right. I ended up doing the final alignment myself and the coach goes straight down a straight road for hundreds of yards without my hands on the wheel.
I'm not saying that your alignment is wrong, just that truck shops deal with trucks and GMCs are not that.
I admire your tenacity in sticking with the coach and trying to get it right. Did you know that Alex Ferrara, who was a helluva smart guy and good mechanic, was going to sell his coach because of handling issues? Then he went to a GMCMI convention and Dave Lenzi identified his problem with literally a glance. I don't know if someone already posted a link to Rob Mueller's write up on how to check all of the steering and suspension components that could affect steering. It takes two people to perform and a good bit of time, but if you haven't gone through Rob's process you should.
Keep with it, Brian! We're all rooting for you.
